THUNDER BAY - The district health unit has determined suspected cases of food-borne illness were not acquired through a local sushi bar.
Last week the Thunder Bay District Health Unit announced they were investigating Bento Sushi, located inside the Real Canadian Superstore, after four people were reported to be ill after consuming the food on March 28.
Neither food or stool samples tested positive for food-borne illness but stool samples did test positive for norovirus.
While norovirus can be spread through food, the health unit determined the incubation period ruled out Bento Sushi as being the cause. Norovirus is most commonly spread through contaminated surfaces and then ingesting the virus.
The health unit advises the spread of norovirus can be prevented by washing hands frequently, disinfecting surfaces, rinsing fruits and vegetables and that individuals who are ill not prepare food for others.
